substituted for abandoned application Serial No. 419,446, November 17, 1941. This application December 6, 1945, Serial No. 633,162

Thisinvention relates to improvements in Rug Cleaning and Shampooing Machines and is a substitution of my earlier abandoned application Serial No. 419,446, filed November 17, 194.1.

One of the objects of this invention is to provide an efficient machine Y or apparatus adapted to be manually moved or reciprocated for the purpose of efficiently scrubbing or shampooing 4surfaces to be cleaned, and particularly l for the purpose of scrubbing and shampooing with a suitable cleaning agent the nap surfaces rotatable head adapted to scrub a given area orV the nap of a rug, carpet or the like with a suitable liquid cleaning material for the purpose of loosening, suspending or dissolving dirt or grease in such nap and simultaneously squeegeef ing the same area to remove from said area ofthe'rug the spent cleaning material together vlith'its load of dirt and grease.

Another object of my invention is, in a device -foi the character above speciied, to utilize a vacuum or suction element for applying suction or vacuum at the axis of the rotatable head, to

collect or gather the spent liquid cleaning material, dirt and grease at such axis and to rei move the same.

' Another object of my invention is, in a device of the character specied, to utilize a rotatable motor-driven cleaning head, to provide said head lwith scrubbing brushes to scrub a given surface and employing squeegee devices operating over the same area for guiding and deflecting the used cleaning iiuid and dirt to a removal center prefv erably located at the axis of the rotatable head.

' Still another object of my invention is,- in a device of the character described, to utilize a squeegee device having one portion extending along the outer perimeter of a revolvable head to provide, along said perimeter, a perimetric protecting apron to prevent splashing or centrifugal spreading of the cleaning material and Vvanother-continuous portion extending from said perimetric portion to an axially located suction pipe. A

VAStill another object oi my invention is to `utilizeA a'squeegee having, in combination, an axially-located suction element, a perimetric protecting apron and a continuous delecting portion comprising a curvedv portion of lesser 4 Claims. (Cl. 15-321) diameter thanthe rotating head having its ,curve disposed in the direction of rotation of the head.

Another object of my invention is, inv adevice of the character described, to provide on a motordriven rotatable head a plurality of squeegee elements each comprising a perimetric circular section and a curved ,inwardly-extending arcuate section having its concave side facingjin the direction of movement of the head.

Still another object of my invention is, von a motor-driven rotatable head, to provide a squeegee device of the character described, in oombination with cleaner-.feed perforations arranged within the perimetric protective section of the squeegee device.

Still another objectv of my invention is to provide, in combination with a sectional squeegee device of the type hereinabove specified', a segmental brush coveringV areas y,at opposite sides of the deflecting section of the squeegee device.

Another object of my invention is to provide a plurality of segmental brushes extending vbetween said deflectingsqueegee portion and said liquid feed periorations, and to provide liquidguiding channels between said segmental brushes and adjacent to said deflecting squeegee sections.

With these and other objects in view the invention comprises the combination of members vand arrangement of parts so combined, asv to co-act and cooperate With eachother in the performance of the `functions and the accomplishment of the results herein contemplated, and Vcomprises in one of its adaptations the species or preferred form illustrated in the accompanying drawings, in which: y Y

Referring now to these drawings which illus- .Figga trate a preferred embodiment of my invention, I indicates a portable platform composed of Wood or other suitable material and having a removable handle bar 2 preferably having mounted thereon a cleaning tank 3 and adapted to be engagediin a pipatting suitably mounted on a base '4' on theiplatfprm I. RevolvablyV mounted beneath the platform I on 'an axially disposed pipe shaft 5 is a revolving head 6 provided on its under surface with brushes 'I land a squeegee element comprising a perimetricjportion'Bajpositioned at the perimeter of the head outside :of the scrubbing brushes and one orJnore inwardlyextending arcuate portions Sa' 'continuous with the perimetric portion Ba which :are .adapted simultaneously to contact with .,a-prug, :carpet :for other similar material to be cleaned. YThe head 6 is revolved by a motor 9 through shat, beveled gears IU, I,.stub shaft II mounted in bearing I2. and .havingat its lower end a sprocket t 3 which 'transmitsnrotion through the chain 'I4 '.With a sprocket f5 mounted aXia-llyjof the vpipe .Shaft 5.

so fthatjliquid coming 'from the tank 3 through f the pipel will, upon the'rotation of the head 6, ",becallsed to move 'down on to the rug ata posi- .tion inside said perimetric nsqueegee portion 8. 'The 'liquid thus dropping onto the Y'surface cf the rug willbe brushed .into the nap vo'i' therug by .the .adjacent brushes to loosen any dirt orgrease .contained therein and `the spent material will then comein contact Withthe squeegee'members '8, .8' and paused to V.be deflected toward the con- `duit .5 which is provided with suitable vacuum `or ,suction means to suck up the spent or eX- nausted liquid. As shown, a plurality of pair of squeegee.elements .or ,members yare each composed lof .a perimetric `portion Se and an inwardly- .extending arcuate portion .8N continuous there- .withand said arcuate portions each have `concave .sections .8V Afacing in the .direction of rotation ,so as to bound concave head areas and portions .of lsaid scrubbing brushes extending into said .concave head areas. As illustrated, the pipe 5 `i-s connected with a portable vacuum tank I'I kthrough a long flexiblehose I8. As illustrated,

.the vacuum tank I'I comprises a .suitable metallic tank having mounted at its upper end a cover AI9 .on which is vmounted a conventional vacuum element comprising a .motor 29a and fan 23h adapted to cause .a suction inside the tank and through the hose I8 and pipe 5 to ia. position .closely adjacent to the surface of the rug and to the insideends of the squeegee members which are suitably positioned in relation to the pipe and `cause the spent material to be passed through r`gates 8a to a position ,directly beneath the pipe which, through its suction means hereinabove described, then sucks up the material and passes the same tothe .tank-I1. The suction tank has a suitably controlled air outlet 2|.

The .operation of my device is as follows: the

tank 3 is filled with .a suit-able cleaning material and manually moved into position over a rug surface to be cleaned. The motori) is then started and through the perforations I6. This material .would then be thoroughly brushed into the rusr by the segmental brushes 'I and the same area. of the rug which is so brushed with the said material will be squeegeed by squeegee members 8, 8 and the spent material and dirt will be deected inwardly toward the axis of the machine by the members 8, 8, a large part of the material,

'a'ftertthebrushing, fllowing vthechannels 22 to "the gates lor entrances 8a 'between 'adjacent segmental squeegee members to an axial position rdirectly beneath the pipe 5 through which vacuum `or isuctionbeing applied will suck up the spent and deflected material and cause the same to be conducted into the vacuum tank I7. Of course,

"'the'machine`or apparatus will be manually moved `.or.reciprocatedgfrom spot to spot over the rug so that the entire :rug will be treated and thoroughly cleaned. It will be seen that in accordance with my invention the used or spent cleaning material with its .load of dirt; and grease is conducted inwardly bythe deiiecting portions of the v'sduee'gee 'members VAand that the iperim'etric portions of thesqueegee members 'not only .assist in deflecting 'the `material bui-,prevent suchimaterial from v:being scattered or broadcast 'through centrifugal motion -of the 'head Vfand `denitely act as conning elements as -Well as squeegee members.

By moving 'the portable apparatus'with `a reciprocatory motion the cleaningliquid-m'ay beth'oroughly brushed into Vlthe rug both 'bythe 'reciprocating and revolving .motions andthe cleaning liquid with its 'load `of dirt will be coniined and prevented from -spreading by 'the rotation 'of the head and furthermore will 'be continuously -deiiected by the squeegees toward the center :and lsucked up by the tube 5.
